Feedwater heater - Wikipedia

A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system. This reduces plant operating costs and also helps to avoid thermal shock to the boiler metal when the feedwater is introduced back into

Boiler Post Purge - tekmar control s

Boiler Post Purge When a boiler is turned off some heat remains in the mass of the boiler. If the flow through the boiler is stopped at the same time the boiler is shut off, the residual heat is lost. Therefore, after operation of the boiler the residual heat in the boiler should be purged to the system in order to decrease standby losses.

My Oven Is Not Heating Up to the Right Temperature

Apr 25, 2015· Set your oven to 350° (you can use another temp but this is an easy one to work with). Let the oven pre-heat, and then give it another 20 minutes or so to make sure it is at its final temperature (for the current setting). Check the reading on the oven thermometer to see if it reads 350°, or something higher or lower like 325° or 375°.
